BLEACHING-VAT.

SPECIFICATION :forming part of Letters Patent No. 704,402, dated July 8, 1902.

Application filed March 15, 1901. Serial No. 51,370. (No model.)

To (LZ whom, it may concern.'

Be it known that we, FRANK TAYLOR, residing at Doagh, county of Antrim, ALEXAN- DER COOKE, residing at Notting Hill House,

Belfast, and BOUGHEY WILLIAM DOLLING MONTGOMERY,residiug at Fort Villiam Park, Belfast, Ireland, subjects of I-Iis Majesty the King of England, have invented a certain new and useful Improvement in Bleaching and 1o Like Vats, of which the following is a speciication.

Our invention relates to au improvement in bleaching and like vats applicable for use when bleaching loose fibers and yarns, 'piece I5 goods, and the like, such vats being particularly applicable when bleaching by the chlorin process or other process where reagents can be reused in bleaching piece goods or cotton or linen yarns orthe like in the form of zo banks of vegetable or animal iibers.

By the employment of the apparatus the hanks or the like require less handling during the bleaching or like` process than heretofore, and consequently a saving in labor is effected.

The apparatus comprises a series of lbecks or vats for containing the bleaching liquors and the necessary reagents, having rods, rollers, or the like on which the yarns are loosely carried, (or in the case of piece goods suitable Winches or rollers,) together with means for circulating the liquids and changing and refreshing and agitating same.

In the accompanying drawings, Figure l is a side elevation of so Inuch of the apparatus as is required to illustrate the invention. Fig. 2 is a cross-section through one of the vats and connected parts on a larger scale. Fig. 3 is a plan o'f a vat on the scale shown 4o in Fig. 2; and Fig. a is a sectional elevation, on an enlarged scale, of a plug forming part of the circulating means.

Ve employ a number of vats a, across the open tops of which are supported rollers b, the front journals of which, as seen in Fig. 2, may rest in plain bearings on the edge, While the rear journals are extended and rest in bearings c, carried by a beam e, resting between the upright arms or guides ff of brackets g. The journals at this end also carry wormwheels h, engaged by Worms t' on a shaft j, running the entire length of the apparatus. The bearings are preferably formed of or lined with Babbitt or other non-oxidiz ing metal. The beam c has attached to it at its ends chains k 7c, connected to one end of a lever Z, pivoted to an upright fm, the other end of the lever extending across the vat to the point of same and terminating in a han dle. By this arrangement the hanks or the like can be rotated or caused to travel in tho bath or by pulling down. the handle and raising the Worm-Wheels `from the worms their movement in any particular vat can be stopped for inspection or otherwise.

Beneath the series of vats a is a trough n, or it may be a pipe connected to each vat by an open neck n', which is closed by a plug hereinafter described. The trough is connected to a centrifugal orother suitable pump, which draws off the liquors to a suitable settling-tank and to or past refreshing means and delivers them into a similar trough o, situated above the tanks. The pump, settling-tanks, and refreshing means are not shown, as they are devices well understood in the trade, the refreshing means of course being arranged at suitable points and carrying the necessary chemicals to renew the vats as may be required. From the trough o there depends into eachtauk a pipe or neck o', as shown, and the opening to such pipe or neck is provided with a plug of a similar character to that employed for the outlet of the tank. These plugs are pneumatic and are arranged so that a tight joint may be quickly made regardless of any small obstruction or inequality inthe plug-hole. They consist of a cylinder or pipe p, Fig. 4, which in the case of the outlet-plug may be long enough to reach above the level of the vat and in the case of the inlet sufficiently long to be reached from any desired point, such cylinder containing a piston p and a suitable piston-rod and handle p2. The cylinder is provided `with a flange p3, which rests on the top of the neck n' in the case of the outlet or the neck o in the case of the inlet to the tank or directly on the bottom of the vat a or trough o, as the case may be, if such necks are not employed roc to line the openings. Below this flange the cyliuderp is continued and terminates in a second smaller flange 194, capable of passing into the openings or necks, the cylinder p being perforated at p5. The flanges p3 and p4 are grooved at p6, and a piece of rubber tubing q is drawn over the lower flange p4 and secured in the groove of same and in the groove of the upper flange p3 by wiring same thereto or in other suitable ways. Thus an elastic chamber is formed communicating with the cylinder @,so that by forcing Adown the piston after the plug has been loosely put into the opening or neck air will be driven into the chamber and cause it to expand, as shown, forcing the rubber q against the side of the neck or opening. To retain the pressure so exerted, the handle p2 may be held down by a chain r, which is attached to the cylinder p and a loop of which may be carried over the handle or it may be held in other ways.

In place of the piston and operating-handle a flexible pipe may be attached to the stem or cylinder, which will then form only a handle for the plug, such pipe terminating in a small valve, such as used for the pneumatic tires of vehicles and adapted to receive the end or the flexible tube of a hand-pump of any suitable type.

In the trough o are gates or sluices s, vertically movable in guides s s', such gates having rubber-covered edges, so that as they rest between the guides s s a sufficientlytight joint is obtained for the low pressure of liquid in the trough. Each trough is controlled by such a gate. The lower trough 'n is provided with a waste-opening t, which is closed by a sluice-gate u, vertically movable in guides f t. Such sluice-gate carries on its inner face 'a rubber pouch or bag u', having a valve u2 of the class employed for pneumatic tires, so that when deflated the sluice-piece can be dropped into the guides i and be afterward inflated, so that the bag portion partly fills the opening t and closes same regardless of any small obstruction which may be lodged in the opening or on the outer face of the trough.

In operating with the arrangement of vats described No. l may be empty of solution, but loaded with yarn or the like, No. 2 filled with a suitable acid, and No. 3, say, with a permanganate-of-potash solution. The acid from No. 2 is now run out into the trough n and pumped into trough 0, from which it runs into vat l. No. 2 is then lled with yarn and the acid from No. lis similarly pum ped around and after being refreshed on its way is run into vat No. 2. Permanganate solution from No. Sis similarlypumped around and run into No. l, and No. 3 is then loaded with yarn and charged with acid drawn from 2 and suitably refreshed, and so on until the round :is completed and the necessary shade of white or discoloration is ob tained, when the apparatus is unloaded and a fresh supply of yarn introduced. The gates s determine the distance the liquors travel along the trough o. It will be seen that by the arrangement of' the several vats all may be more or less kept filled with goods and a continuous series of steps carried on. The fall of the liquids into and from the vats and the travel of same provides the necessary agitation to eect the mixing of same and prevent settling.

l. In combination,a vat having a dischargeopening, a delivery-trough for liquids above same having a discharge-opening above the trough, a discharge-trough beneath the vat,

plugs for the discharge-openings both of the delivery-trough and the vat each comprising a cylinder,means for compressing air in same, a flange on the cylinder seating on the receptacle, a perforated extension of the cylinder below such flange, a further smaller flange adapted to pass into the opening of' the receptacle and an elastic surrounding wall for the chamber formed between such flanges adapted to be expanded in the opening by the air-pressure in the cylinder.

2. In combination, a liquid-receptacle having an opening therein, a plug for such opening comprising a cylinder, piston, and operating means for the latter', a flange on the cylinder seating on the receptacle, a perforated extension of the cylinder below such flange, a further smaller flange adapted to pass into the opening of the receptacle and an elastic lsurrounding Wall for the chamber formed between such flanges adapted to be expanded in the opening by the action of the piston.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
